title: Confined bulklike longitudinal optical phonon modes in right triangular quantum dots and quantum wires.
abstract: Under the dielectric continuum model, the confined bulklike longitudinal optical phonon modes and electron-optical-phonon interaction of the isosceles right triangular (45°-45°-90°) quantum dot (wire) and hemi-equilateral triangular (30°-60°-90°) quantum dot (wire) are studied. The analytical expressions for the confined bulklike longitudinal optical phonon eigenfunctions are deduced. After having quantized the polarization eigenvectors, we derive the Hamiltonian operators describing the confined bulklike longitudinal optical phonon modes and their interactions with electrons. The potential applications of these results are also discussed.
